the peribranchial sinuses. He finds by injection a communication 
between the latter sinuses and the portal heart, but does not describe 
its nature. This point, however, is cleared up by what I have already 
stated. 
ALLEN, in his recent paper on the caudal heart of Bdellostoma, 
fails to etablish any direct communication between the veno-lympha- 
tics and the arteries. He found great quantities of red corpuscles in 
the veno-lymphatics of embryos, but only a few in the adult. 
Mozesko describes the anterior cardinal of Petromyzon as arising 
by the union of superficial and deep vessels, exactly as in Myxine. 
He regards the deep anterior cardinal only as a communicating channel 
between the infra-capsular sinus and the anterior cardinal, and not 
as a definite blood vessel. The inferior jugular has a paired origin, 
and is connected with the infra-capsular sinus as in Myxine, but 
apparently not in the same way. He considers that the veno-lymphatics 
are really modified veins and develop as such. Fishes are said to 
possess no true lymphatics, which occur for the first time in Amphibia. 
MOoZEIKO and ALLEN agree that the veno-lymphatics of Fishes cannot 
be compared with the lymphatics of other vertebrates.

Meine Untersuchungen beziehen sich auf zwei Schildkrötenarten: 
eine Landschildkröte (Testudo graeca) und ‚eine Wasserform (Emys 
lutaria). Auf die Innervation hin wurde die Zunge, der Gaumen, 
der Randwulst der Mundhöhle und die Haut untersucht. Es wurden 
in diesen Organen mehrere Arten der Nervenendigungen gefunden. 
Freie Nervenendigungen. Ich beginne mit der Beschreibung 
der einfachsten Form d. h. mit den freien Endigungen. Solche intra- 
epitheliale Endigungen der Zunge entstammen myelinhaltigen Nerven-
